Mrs. Porter had also been a Girl Scout leader and volunteered at her church.

After her husband retired in 1983, she joined him in genealogical research, which took the couple to England, France, Scotland, Austria and Germany "to research his and her ancestries — a passion they both shared," said Ms. Carey.

They also liked sailing the Chesapeake Bay aboard their vessel, Star of the Sea, from Gibson Island.

"She was very actively involved with her children, grandchildren and even her great-grandchildren," said Ms. Carey, who said her grandmother cross-stitched a wall-hanging with her credo: "Make your home a retreat to which a son or daughter can return in triumph or defeat, in victory or disgrace, and know they will be loved and respected."

Mrs. Porter was an active communicant of Holy Comforter Episcopal Church, Bellona and Seminary avenues, Lutherville, where a memorial service will be held at 11 a.m. Tuesday.

In addition to Ms. Carey, Mrs. Porter is survived by her husband of 66 years; a son, Richard Alan Porter of Guilford, Conn.; two daughters, Barbara Porter Carr of Lutherville and Carolyn Porter Adkins of Lancaster, Pa.; eight other grandchildren; and four great-grandchildren.
